SFC

[Paul Koukos]

I ran this program at a suggestion from a friend, and it found a bunch of files that were missing, copied them from the CD and I thought that will fix the problems.

I did the same thing a few days later, and it still finds DLL files that are missing.

Am I doing something wrong here.

Thanks for any help.

Hi, Paul.

HOW are you running SFC?

There are several optional switches that can be used with SFC, but the only
one most people need is /scannow. To see all the options, open a "DOS"
window and type sfc /?.

SFC should be needed only rarely - or never. SFC /scannow should copy any
files it needs from the CD or from internally cached update files. You
should not need to manually copy any files. And there should be no need to
run it again until something else in your computer causes other files to be
deleted or damaged. Any idea what might be causing your dll files to go
missing? Are you running a cleanup program that may be too aggressive?

Hi, Paul.

As I said in the message I just posted in your other thread, a visit to
Windows Update might clear things up for you.

Each time WU downloads and installs an update, it puts the updated copy in
both the working folder (System32) and the cache (System32\dllcache), and
updates its internal database to refer to the new version. It sounds like
your database is somehow out of sync and doesn't know which version of each
file is the latest and greatest. :>( SFC may be copying old, original
files from your CD-ROM, overwriting newer files from Windows Update - or
something similar.

For the official word on how SFC is supposed to work, see the online version
of the Windows XP Pro Resource Kit:
System File Checker
http://www.microsoft.com/resources/...Windows/XP/all/reskit/en-us/prpt_pt7_lxdz.asp

and drill down to:
Welcome > Part VII Appendices > Appendix D Tools for Troubleshooting >
System File Tools > Windows File Protection

This reference also refers you back to WinXP Help and Resource file already
on your computer, so you might want to check that first.

Does your WinXP CD-ROM include SP1?
